Urban skiing consists of sliding or grinding your skis on rails, ledges, etc. outside of ski resorts/areas. Urban has much more of a risk factor than regular park skiing due to harder terrain. You can spot urban features in such ski movies as Level 1's "Eye Trip" and Poor Boyz Production's "Revolver."
